How to synchronize your Delta Chat account on your phone with your computer desktop?
- Android/Linux/Windows -
You want to use your Delta Chat account simultaneously and synchronized on your Android phone and on your computer desktop as well. Note that for iPhone/Mac Desktop there is a separate HOWTO.
Follow the instructions and you will be able to seamlessly switch between your devices with your chat history in sync:
In Delta Chat click on the menu (upper right corner) → Settings → Advanced and enable Send copy to myself (necessary for seeing sent messages on your other device as well).
Create a backup on your phone: in Delta Chat click on the menu → Chats and Media → scroll down and click on Back Up Chats to External Storage. Now you might need to type in the password or use the finger print that you also use to unlock your phone. Click on Start Backup. This will create a backup file in your downloads folder on your mobile phone, with a name like delta-chat-[DATE].bak
Connect your mobile phone to your computer via USB cable. A permanent notification will appear on your phone. Select transfer file mode to transfer the backup from your phone to your computer/ tablet, e.g. to downloads folder as well.
Please do NEVER take short cuts such as sending the DC backup via cloud, e-mail or messenger because the backups are not encrypted thus not protected. If someone gets access to your backup they could for example impersonate you
Open Delta Chat on your Desktop and DO NOT put in your email address or password. Instead click on Import Backup (center bottom) on the start screen. A window will open, navigate to your Android phone → download folder and click on the backup file you just created on your phone (delta-chat-[DATE].bak). You synchronized account will open immediately. Please delete your backup once you set up your device.
